Devices, methods, and systems for providing interactivity with digital signs

ABSTRACT

A device, method, and system for providing interactivity with a digital sign includes an interactive digital sign configured to display information in response to interactions by a viewer. The viewer may interact with the digital sign using sensors of the digital sign or via use of a mobile communication device carried by the viewer. User data may be used by the interactive digital sign to select the information, which may include advertisements, coupons, directions, and other information. The information may be transmitted to the viewer&#39;s mobile communication device.

BACKGROUND

Digital signs are used to display information, such as advertisements,notifications, directions, and the like, to people in the near vicinityof the sign. Unlike static billboard signs, the information displayed ona digital sign may be programmed to change over time. For example, adigital sign may be configured to display certain information one dayand different information on a different day. Although the informationdisplayed on typical digital signs may change over time, such changingof information is generally pre-defined or random such that a viewer ofthe digital sign has limited interaction with the information displayed.

Mobile communication devices are becoming ubiquitous tools for personal,business, and social uses. While the primary use for many mobilecommunication devices remains person-to-person communication via voiceor textual technologies, modern mobile communication devices areequipped with increased processing power and data storage capability toallow such devices to perform advanced processing. For example, manymodern communication devices, such as typical “smart phones,” arecapable of executing specialized operating systems and associatedsoftware applications. Additionally, many modern mobile communicationdevices are capable of connecting to various data networks, includingthe Internet, to retrieve and receive data communications over suchnetworks.

Similarly, the microphone 334 may also beincorporated into the mobile communication device 104 and be embodied asany type of audio sensor capable of capturing audio data (e.g., speechdata) in the vicinity of the mobile communication device 104.

Referring back to FIG. 1, in some embodiments, the system 100 may alsoinclude a digital sign management server 110, which manages the variousdata used by the interactive digital sign 102. The digital signmanagement server 110 may be embodied as any type of data server capableof performing the functions described herein and includes components(e.g., processors, memory devices, etc.) commonly found in such dataservers. The interactive digital signs 102 may communicate, periodicallyor responsively, with the digital sign management server 110 over anetwork 106 to retrieve various data. The network 106 may be embodied asany type of suitable data network including, for example, a wirednetwork, a wireless network, a local area or wide area network, apoint-to-point network, an ad hoc network, and/or other data networkacross which information may be shared between the interactive digitalsigns 102 and the digital sign management server 110.

The digital sign management server 110 may maintain a database ofdigital advertisements 112, digital coupons 114, and/or other digitalinformation (e.g., directions, maps, menus, etc.) from which thecorresponding information stored on the interactive digital sign 102 maybe updated. As such, in use, each interactive digital sign 102 may storeonly a small selection of the available digital advertisements anddigital coupons as discussed above. If the interactive digital sign 102determines that additional or other digital advertisements or digitalcoupons are required (e.g., based on a viewer's context or user datareceived from the mobile communication device 104), the interactivedigital sign 102 may communicate with the digital sign management server110 to receive additional digital advertisements 112, digital coupons114, and/or other digital information.

In some embodiments, the mobile communication device 104 may alsocommunicate, periodically or occasionally, with the digital signmanagement servers 110 over a network 108 to update, or otherwisemaintain, user data on the digital sign management server 110. Similarto the network 106, the network 108 may be embodied any type of wiredand/or wireless data network. In the illustrative embodiment, thenetwork 108 is embodied as a global, publicly-available network such asthe Internet.

The digital sign management server 110 may maintain a database of userdata, which may include user profile data 120 and user preference data122. The user profile data 120 is similar to the user profile data 320,and the user preference data 122 is similar to the user preference data322, stored on the mobile communication device 104. The digital signmanagement server 110 may also maintain sign profile data 124 thatidentifies characteristics of individual interactive digital signs 102such as sign type, sign location, supported features, supportedinteractions, and/or other characteristics of the interactive digitalsigns 102. The mobile communication device 104 may query the digitalsign management server 110 to access such sign profile data 124 todetermined, for example, the location of the nearest interactive digitalsign 102 and its capabilities.

The system 100 may also include one or more advertiser client computers130, which may be embodied as any type of computer or computing devicecapable of performing the functions described herein. The advertiserclient computer 130 is usable by an advertiser to communicate with thedigital sign management server 110 over the network 108 to store and/orupdate the server 110 with digital advertisements 132, digital coupons134, and/or other digital information 136, which may be stored on theadvertiser client computer 130. In this way, new digital advertisements,coupons, and information may be displayed on the interactive digitalsigns 102 and presented to the user.

Referring now to FIG. 4, in one embodiment, the interactive digital sign102 may establish an environment 400 during operation. The illustrativeenvironment 400 includes a viewer context determination module 402, auser interaction module 404, and a communication module 406, each ofwhich may be embodied as software, firmware, hardware, or a combinationthereof. As discussed in more detail below, the viewer contextdetermination module 402 is configured determine the context of a viewerof the interactive digital sign 102 based on the sensor signals receivedfrom the sensors 212. For example, the viewer context determinationmodule 402 may detect the presence of a viewer within a pre-definedrange of the interactive digital sign 102, determine a personalcharacteristic of the viewer (e.g., gender, age, hair color, etc.),determine whether the viewer has performed a pre-defined physicalgesture (e.g., a hand waving gesture), and/or determine other contextparameters about the viewer as a function of the sensor data. Asdiscussed above, the sensor data generated by the sensors 212 may beembodied as any type of data from which the context parameters of theviewer may be determined including, but not limited to, image data,video data, audio data, proximity sensor data, communications data(e.g., data from the communication module 406), and/or other sensordata.

The viewer context determination module 402 provides the generatedcontext parameters to the user interaction module 404, which may selectinformation for display and facilitate interaction with the viewer(and/or the mobile communication device 104 carried by the viewer) basedon the context parameters. The illustrative user interaction module 404includes an advertisement module 410, a coupon module 412, aninformation module 414, a navigation module 416, and a graphics module418, each of which may be embodied as firmware, software, hardware, or acombination thereof. The advertisement module 410 manages the selectionand display of digital advertisements 220 based on the contextparameters of the viewer (e.g., the viewer's presence, a physicalgestures performed by the viewer, etc.) and/or the user data receivedfrom the mobile communication device 104 (e.g., the user's profile orpreference data). Similarly, the coupon module 412 manages the selectionand display of digital coupons 222 based on the context parameters ofthe viewer and/or the user data. The information module 414 manages theselection and display of other digital information 224 based on requestsfor such information received from the user (e.g., voiced orgesture-based requests received from by sensors 212, requests receivedfrom the mobile communication device 104, etc.). The navigation module416 manages the determination and presentation of directions and othernavigational data in response to requests for directions received fromthe viewer. To do so, the navigation module 416 may maintain a suitabledigital map, which may be presented to the user in association withdirections determined by the navigation module 416. The graphics module418 manages the presentation of, and viewer's interaction with,multimedia data on the display 208. In some embodiments, for example,the graphics module 418 may present a digital avatar on the display 208with whom the viewer may interact to receive information. Additionally,as discussed in more detail below, the graphics module 418 may receivemultimedia data from the mobile communication device 104 (e.g., video,graphics, presentations, computer games, digital avatars, etc.) anddisplay or execute the multimedia to allow the viewer to interact withthe transmitted multimedia on the display 208.

The communication module 406 facilitates the bi-directionalcommunication between the interactive digital sign 102 and the mobilecommunication device 104, as well as other remote devices such as thedigital sign management server 110. In the illustrative embodiment, thecommunication module 406 includes a markup language extension 420, whichis usable by the user interaction module 404 to identify parameters oftransmitted and received information. For example, should the mobilecommunication device 104 request information pertaining to thecapabilities of the interactive digital sign 102, the response sent bythe interactive digital sign 102 may include the capabilities identifiedby special header tags of the markup language extension 420 as discussedin more detail below.

Referring now to FIG. 5, in one embodiment, the mobile communicationdevice 104 may establish an environment 500 during operation. Theillustrative environment 500 includes a detection module 502, a digitalsign interaction module 504, and a communication module 506, each ofwhich may be embodied as software, firmware, hardware, or a combinationthereof. The detection module 502 is configured to detect the presenceof an interactive digital sign 102 within the vicinity of the mobilecommunication device 104. In some embodiments, the detection module 502may monitor local wireless networks and/or communications received bythe communication module 506 to determine the presence of an interactivedigital sign 102. In this way, the detection module 502 may performautomatic or near-automatic detection of an interactive digital sign102.

The digital sign interaction module 504 facilitates interaction betweenthe mobile communication device 104 and the interactive digital signs102. For example, in some embodiments, the mobile communication device104 may transmit user data, such as the user profile data 320, the userpreference data 322, and/or the shopping data 324 to the interactivedigital sign 102. Additionally, the digital sign interaction module 504may allow the user to interact with the interactive digital sign 102 bysubmitting questions, requests, responses, and/or instructions to theinteractive digital sign 102 as discussed in detail below. The digitalsign interaction module 504 may further receive responses, and otherdata, from the interactive digital sign 102 and display such data on thedisplay 330.

Similar to the communication module 406 of the interactive digital signs102, the communication module 506 facilitates the bi-directionalcommunication between the mobile communication device 104 and theinteractive digital signs 102, as well as other remote devices such asthe digital sign management server 110. In the illustrative embodiment,the communication module 506 includes a markup language extension 520,which is usable by the digital sign interaction module 504 to identifyparameters of transmitted requests and/or other information as discussedin more detail below.

Referring now to FIG. 9, in use, the interactive digital signs 102 mayexecute a method 900 for updating information locally stored on theinteractive digital sign 102 from the digital sign management server110. The method 900 begins with block 902 in which the interactivedigital sign 102 determines whether updates are available from thedigital sign management server 110. To do so, the interactive digitalsign 102 may query, periodically or occasionally, the digital signmanagement server 110 for updates. Additionally or alternatively, thedigital sign management server 110 may notify the interactive digitalsign 102 when updates are available.

If no updates are available, the method 900 loops back to block 902 inwhich the interactive digital sign 102 continues to monitor for updates.However, if interactive digital sign 102 determines that updates areavailable, the interactive digital sign 102 establishes a communicationconnection with the digital sign management server 110 over the network106 in block 904. In some embodiments, such communication connection maybe a secured connection. In block 906, the interactive digital sign 102may transmit a digital sign identifier and/or location information thatidentifies the location of the digital sign 102 and/or other informationusable by the digital sign management server 110 to identify theupdate-requesting interactive digital sign 102.

Subsequently, in block 908, the interactive digital sign 102 receivesupdated data from the digital sign management server 110, which issubsequently stored in the local data storage 210 of the interactivedigital sign 102 in block 918. For example, the interactive digital sign102 may receive new or updated digital advertisements in block 910, newor updated digital coupons in block 912, and/or new or updatedadditional digital information in block 914 from the digital signmanagement server 110. Additionally, in some embodiments, theinteractive digital sign 102 may locally store and maintain user profileand preference data. In such embodiments, the interactive digital sign102 may receive new or updated user profile and/or preference data inblock 916. After any received updated data is locally stored in block918, the method 900 loops back to block 902 in which the interactivedigital sign 102 continues to monitor for updates.

Referring now to FIGS. 10 and 11, in use, the interactive digital signs102 may also execute a method 1000 for facilitating interactivity withthe digital sign 102. The method 1000 begins with block 1002 in whichthe interactive digital sign 102 displays random and/or pre-defineddigital information on the display 208. The random/pre-defined digitalinformation displayed in block 1002 may be embodied as any type ofdigital information, such as digital advertisements and/or information,which may also change periodically. In block 1004, the interactivedigital sign 102 monitors for the presence of a viewer within thevicinity of the digital sign 102. To do so, in block 1006, theinteractive digital sign 102 receives sensor data from the sensors 212and determines viewer context data from such sensor data in block 1008.The context data of any present viewer may include any type of data thatidentifies a context parameter of the viewer. For example, theinteractive digital sign 102 may analyze the images generated by thecamera 230, using a suitable facial recognition, pattern recognition,edge detection, or other image analysis process, to determine physicalcharacteristics of the viewer (e.g., the presence of the viewer, gender,age, height, weight, hair color, and/or other physical characteristic)and/or non-physical characteristics of the viewer (e.g., the viewer'smood, emotional state, reactions, body language interpretation, level ofinterest, and/or other emotional or non-physical characteristic).Additionally, the interactive digital sign 102 may analyze the audiodata generated by the microphone 232 to determine physicalcharacteristics (e.g., the viewers age, gender, nationality, location,etc.) and non-physical characteristics (e.g., the viewer's mood,emotional state, level of interest, etc.).

In block 1010, the interactive digital sign 102 determines whether aviewer is present based on, at least a portion of, the determinedcontext data. For example, the interactive digital sign 102 maydetermine the presence of the viewer within a pre-defined range based onsensor data received from the camera 230 (e.g., whether a viewer ispresent in the digital image generated by the camera), from themicrophone 232 (i.e., whether a viewer is speaking), from the proximitysensor 234 (e.g., whether a viewer is moving), and/or from the networkanalyzer 236 (e.g., whether a viewer is operating the mobilecommunication device 104). In this way, a viewer may approach theinteractive digital sign 102 (or one of the display screens 250) andautomatically be detected and interacted with by the interactive digitalsign 102.

If no viewer is determined to be present in block 1012, the method 1000loops back to block 1002 in which the interactive digital sign 102 againdisplays random or pre-defined digital information. However, if a vieweris determined to be present in block 1012, the method 1000 advances toblock 1014 in which the interactive digital sign 102 retrieves digitalinformation for display on the display 208 as a function of thedetermined context parameters of the viewer. To do so, in block 1016,the interactive digital sign 102 determines which display screen 250, orselection of display screens 250, to allocate for use with the newlydetected viewer. The interactive digital sign 102 may select the displayscreen(s) 250 based on, for example, the context data of the viewer. Forexample, the interactive digital sign 102 may select the display screen250 determined to be closest to the viewer, at eye-level with theviewer, or based on other context data of the viewer. As discussed abovewith regard to FIGS. 6-9, the digital interactive sign 102 may selectmultiple display screens 250 for use with displaying content informationto the detected viewer. Such selection of display screen(s) 250 maychange based on the interaction of the viewer. For example, if theviewer works around the interactive digital sign 102, the display screen250 used to display content to the viewer may change so as to follow theviewer about the digital interactive sign 102. Additionally, in someembodiments, the viewer may select the one or more display screens 250with which to interact.

After the display screen(s) has been determined or selected, theinteractive digital sign 102 may retrieve and display one or moredigital advertisements 220 in block 1018, retrieve and display one ormore digital coupons 222 in block 1020, and/or retrieve and displayadditional digital information 224 in block 1022. The interactivedigital sign 102 may retrieve the selected information from the localdata storage 210 and/or from the digital sign management server 110based on any suitable context parameter. For example, in someembodiments, the interactive digital sign 102 may select the informationto be retrieved based on a physical gesture performed by the viewer(e.g., a hand waving gesture), a physical characteristic of the viewer(e.g., gender, age, hair color, etc.), or other context parameterassociated with the viewer and determinable based on the sensor datagenerated by the sensors 212.

After the selected digital information has been displayed on the display208 in block 1014, the method 1000 loops back to block 1004 to continuemonitoring for the presence of the viewer. Additionally, the method 1000may advance to block 1024 in which the interactive digital sign 102contemporaneously monitors for the presence of a local mobilecommunication device 104 (e.g., the device 104 of the viewer). To do so,the interactive digital sign 102 may periodically broadcast a query,notification, or other communication ping and determine the presence ofa local mobile communication device 104 based on a response to suchbroadcast communication. Additionally or alternatively, the interactivedigital sign 102 may monitor a wireless communication network on whichthe interactive digital sign 102 is located for the presence of a localmobile communication device 104. If no local mobile communication device104 is detected in block 1026, the method 1000 loops back to block 1004to continue monitoring for the presence of the viewer. However, if alocal mobile communication device 104 is detected, the method 1000advances to block 1028 in which the interactive digital sign 102establishes a bi-directional wireless communication link with thediscovered mobile communication device 104. Such bi-directional wirelesscommunication link may be embodied as an ad-hoc communication link, apoint-to-point communication link, a communication network link, and/orother wireless communication link that facilitates bi-directionalcommunication between the interactive digital sign 102 and thediscovered mobile communication device 104.

After the wireless communication link is established in block 1028, themethod 1000 advances to block 1030 (see FIG. 11) in which theinteractive digital sign 102 may request user data from the mobilecommunication device 104. The user data may be embodied as any type ofdata stored on the mobile communication device 104 and usable by theinteractive digital sign 102 to select personalized digital information(e.g., digital advertisements, coupons, etc.) for display. In theillustrative embodiment, the interactive digital sign 102 may receiveuser profile data in block 1032, user preference data in block 1034,and/or shopping list data in block 1036. As discussed above, the userprofile data may be embodied as data that defines personalcharacteristics of the viewer, the user preference data may be as anytype of data that identifies preferences of the viewer, and the shoppinglist data may embodied as any type of data that identifies products orservices that the viewer desires to purchase. Of course, additional orother user data may be received by the interactive digital sign 102 inblock 1030 in other embodiments.

In block 1038, the interactive digital sign 102 determines whether tointeract with the mobile communication device 104. In some embodiments,the interactive digital sign 102 may be configured to interact with allmobile communication devices 104 or with only selected mobilecommunication device 104. Additionally or alternatively, the interactivedigital sign 102 may interact only upon receiving an initial request orcommunication from the mobile communication device 104. If theinteractive digital sign 102 determines that no interaction is to occur,the method 100 loops back to block 1024 (see FIG. 10) in which theinteractive digital sign 102 continues to monitor for local mobilecommunication devices.

If, however, the interactive digital sign 102 determines to allowinteraction with the mobile communication device 104, the method 1000advances to block 1040 in which the interactive digital sign 102interacts with the mobile communication device 104 over thebi-directional communication link. For example, in block 1042, theinteractive digital sign 102 updates the selected display screen(s) 250based on the viewer's interaction, user data, and/or context data. Thatis, the interactive digital sign 102 may change which display screen(s)250 are allocated for displaying content to the particular viewer and/orchange the number of display screens 250 used to display content to theparticular viewer. Such selection may be in response to any interactionor data related to the particular viewer. For example, the interactivedigital sign 102 may change the selection and/or number of displayscreens 250 based on the location or movement of the viewer, based on aselection made by the viewer, based the size or type of content selectedfor display to the user (e.g., a selected advertisement may requiremultiple display screens 250 to properly display), based on the size ortype of content received from the viewer for display, and/or on otherinteractions, user data, or context data of the user.

In block 1044, the interactive digital sign 102 may select and displayone or more digital advertisement 220 on the display 208 based on theuser data received in block 1030 and/or the viewer context determined inblock 1008. For example, the interactive digital sign 102 may select anadvertisement based on the user's profile (e.g., the viewer may bedetermined to be a young male) and the user's preferences (e.g., theviewer may like rock music). Additionally, in block 1046, theinteractive digital sign 102 may select one or more digital couponsbased on the user data (e.g., the user's shopping data) and/or viewercontext and transmit the selected digital coupon to the mobilecommunication device 104. In some embodiments, the interactive digitalsign 102 may encrypt the digital coupon for security or privacy purposesand transmit the encrypted digital coupon to the mobile communicationdevice 104, which may subsequently decrypt the encrypted digital coupon.In such embodiments, the encrypted digital coupon may be usable only bythe designated person (e.g., only usable on the specific mobilecommunication device 104) and/or be non-transferable to a third party.As discussed in more detail below, the viewer may utilize the digitalcoupon received on the mobile communication device 104 to aid inpurchases made at a store remote from the interactive digital sign 102.

The interactive digital sign 102 may further receive and respond to arequest for directions in block 1048. For example, in some embodiments,the interactive digital sign 102 may display a digital map, along withdirections, on the display 208 in response to a user's request fordirections to a particular destination and/or in response to other datareceived form the user (e.g., the shopping data). In some embodiments,the interactive digital sign may also transmit the digital map and/ordirections to the mobile communication device 104 in block 1048 suchthat the viewer may review the directions while traveling to thedestination. The interactive digital sign 102 may also receive andrespond to requests for other digital information in block 1050. Suchother digital information may be embodied as any type of digitalinformation displayable on the display 208 and/or transmittable to themobile communication device 104. For example, the additional digitalinformation may include information related to the capabilities of theinteractive digital sign 102, information related to the location of theinteractive digital sign 102, information related to events occurring atlocations near the interactive digital sign 102, information related tostores associated with a digital coupon, and/or other information.

In some embodiments, the interactive digital sign 102 may be configuredto receive multimedia data from the mobile communication device 104 anddisplay the multimedia data on the digital sign 102 in block 1052. Suchmultimedia data may be embodied as any type of multimedia dataincluding, but not limited to, digital video, digital pictures,presentations, and/or other graphics. In this way, a viewer of theinteractive digital sign 102 may utilize the display 208 as a remotedisplay device for the mobile communication device 104. Additionally, insome embodiments, the interactive digital sign 102 may select a digitalavatar or character for display on the display 208 and disseminateinformation to the viewer using the digital avatar in block 1054. Forexample, the digital avatar may interact with the viewer using spokenaudio and be responsive to physical gestures performed by the viewerand/or user data transmitted to the interactive digital sign 102 by theviewer. In some embodiments, the digital avatar may be transmitted tothe interactive digital sign 102 from the mobile communication device104. Further, in some embodiments, the interactive digital sign 102 maybe configured to execute a computer game to allow the viewer to play thecomputer game using the display 208 in block 1056. The executed computergame may be stored on the interactive digital sign 102 or be transmittedthereto from the mobile communication device 104 in block 1056. In thisway and unlike a static digital display, the interactive digital sign102 facilitates interaction with the viewer and the mobile communicationdevice 104.

In some embodiments, the interactive digital sign 102 may update theuser data in block 1058 after the viewer has completed interaction withthe interactive digital sign 102. For example, the user preference datamay be updated based on such interactions (e.g., which digital couponsdid the viewer accept, which digital advertisements were of interest tothe viewer, etc.). Additionally, in some embodiments, the updated userdata may be transmitted to the digital sign management server 110 forstorage in block 1060. After the user data has been updated in block1058, the method 1000 loops back to block 1024 to continue monitoringfor the presence of local mobile communication devices 104 and to block1004 to continue to monitor for the presence of new viewers.

Referring now to FIG. 12, in use, the mobile communication device 104may execute a method 1200 for registering and communicating with thedigital sign management server 110. Although the method 1200 isdescribed below as registering the user of the mobile communicationdevice 104 with the digital sign management server 110, suchregistration method may be used with individual interactive digital sign102 in those embodiments in which the interactive digital signs 102maintain local user data without assistance of a digital sign managementserver 110.

The method 1200 begins with block 1202 in which the mobile communicationdevice 104 determines whether to register or update user data. If so,the method 1200 advances to block 1204 in which the mobile communicationdevice 104 establishes a communication connection with the digital signmanagement server 110 (or directly with an interactive digital sign102). Such communication connection may be embodied as a securecommunication connection in some embodiments. In block 1206, the mobilecommunication device 104 transmits the user profile data 320 and/or userpreference data 322 (see FIG. 3) to the digital sign management server110 (or directly with an interactive digital sign 102), which stores theupdated or new user data in the data storage 210. In some embodiments,the mobile communication device 104 may also transmit shopping data 324to the digital sign management server 110 (or directly with aninteractive digital sign 102) in block 1208.

After the user of the mobile communication device 104 has registeredwith the digital sign management server 110, the method 1200 advances toblock 1210 in which the mobile communication device 104 determineswhether the user has requested digital sign profile information. Thedigital sign profile information may identify characteristics of theinteractive digital signs 102 such as the location of the nearestinteractive digital sign 102, the capabilities of the interactivedigital signs 102, the digital coupons available from the interactivedigital signs, and other sign characteristic data. Additionally, thedigital sign profile information may include data related to the user'sdigital sign account such as the number of award points obtained, thenumber of digital coupons used, and other account information.

In some embodiments, the mobile communication device 104 may determine acurrent location of the device 104 (e.g., using a global positioningsystem circuit or other location determination circuit or module) inblock 1212. Alternatively, the user may supply the current location orother location of interest, which may be used to determine nearbyinteractive digital signs 102. In block 1214, the mobile communicationdevice 104 may obtain and/or request additional interactive digital signcriteria. Such criteria may include any data usable to identify digitalsign profile information including, for example, the identityinformation of the user (e.g., an e-mail address), digital signpreferences of the user (e.g., full-featured signs, interactive sighs,etc.), digital sign capability preferences (e.g., digital coupons),and/or other digital sign criteria.

In block 1216, the mobile communication device 104 transmits a requestfor digital sign profile information using the determined currentlocation and/or additional interactive digital sign criteria. In theillustrative embodiment, the request is transmitted using the markuplanguage extension 520 (see FIG. 5), which identifies the individualrequest parameters. For example, the request may include a header tagthat identifies the user's location or desired location (e.g.,“MyLocation: GPS: xx.xx.xx.xx Address: xxx.xxx.xxx”), a header tag thatidentifies the user's digital sign preferences (e.g., “My Preferences:xxx”), a header tag that identifies the user's account or otheridentification data (e.g., “MyShoppingID: xxxx”), and/or other headertags that identify individual parameters of the request.

In block 1218, the mobile communication device 104 receives therequested interactive digital sign profile information from the digitalsign management server 110 (or directly from the interactive digitalsign 102 as discussed above). In some embodiments, the response istransmitted using a mark-up language extension (e.g., markup languageextension 420 of FIG. 4) to identify individual parameters of therequested information. For example, the response may include a headertag that confirms the location of the user or the desired location(e.g., “GPS-Check: xxx”, “Address-Check: xxx”), a header tag thatidentifies the location of nearby interactive digital signs 102 (e.g.,“Closest Signs: xxx”), a header tag that identifies award points and/orinformation related to digital coupons such as which stores accept thedigital coupons (e.g., “Coupons-and-points: xxx”), a header tag thatidentifies an answer or other data related to a previous question orrequest (e.g., “Information: xxx”), and/or other header tags thatidentify individual parameters of the response.

In block 1220, the mobile communication device 104 extracts the digitalsign profile information from the response using the head tags of themark-up language extension. The extracted information may besubsequently displayed to the user of the mobile communication device104 in block 1222 and/or stored for later use. In this way, the user mayquery the digital sign management server 110 and/or individualinteractive digital signs 102 for obtain digital sign profile data tohelp the user locate digital signs 102 of interest and/or monitor theirinteraction and accounts.

Referring now to FIG. 13, the mobile communication device 104 may alsoexecute a method 1300 for interacting with one or more interactivedigital signs 102. The method 1300 begins with block 1302 in which themobile communication device 104 monitors for local interactive digitalsigns 102. To do so, the mobile communication device 104 may monitor fora query, notification, or other communication ping or heartbeat signalreceived directly from an interactive digital sign 102. Additionally oralternatively, the mobile communication device 104 may search for awireless communication network associated with the interactive digitalsign 102 and determine the presence of the interactive digital sign 102based on the existence of such wireless network. In this way, the mobilecommunication device 104 may actively monitor for nearby interactivedigital signs 102 with minimal or no direct interaction from the user ofthe mobile communication device 104. As such, the user of the mobilecommunication device 104 may simply approach the interactive digitalsign 102 to initiate interaction therewith.

If no local interactive digital sign 102 is detected in block 1304, themethod 1300 loops back to block 1302 to continue monitoring for nearbyinteractive digital signs 102. However, if an interactive digital sign102 is detected by the mobile communication device 104 in block 1304,the method 1300 advances to block 1306. In block 1306, the mobilecommunication device 104 establishes a bi-directional wirelesscommunication link with the detected interactive digital sign 102. Asdiscussed above with regard to block 1028 of method 1000, thebi-directional wireless communication link may be embodied as an ad-hoccommunication link, a point-to-point communication link, a communicationnetwork link, and/or other wireless communication link that facilitatesbi-directional communication between the mobile communication device 104and the interactive digital sign 102.

After a wireless communication link has been established with theinteractive digital sign 102 in block 1306, the mobile communicationdevice 104 determines whether a request for the user data stored locallyon the mobile communication device 104 has been received from thedetected interactive digital sign 102 in block 1308. If so, the method1300 advances to block 1310 in which the mobile communication device 104retrieves the requested user data from the data storage 310 (see FIG. 3)and transmits the user data to the requesting interactive digital sign102. As discussed above, the user data may include user profile data320, user preference data 322, and/or shopping data 324. In someembodiments, the mobile communication device 104 may transmit the userdata using the markup language extension 520 (see FIG. 5). For example,the response to the request for user data may include a header tag thatidentifies the user profile data 320, a header tag that identifies theuser preference data 322, and/or a header tag that identifies theshopping data 324. Of course, additional or other mark-up language datatags may be used in other embodiments to identify the individualparameters of the user data.

After the mobile communication device 104 has transmitted the requesteduser data, or if no user data was requested in block 1308, the method1300 advances to block 1312. In block 1312, the mobile communicationdevice 104 determines whether interaction with the interactive digitalsign 102 is desired. In some embodiments, the mobile communicationdevice 104 may be configured to interact automatically with theinteractive digital sign 102 or to interact with the interactive digitalsign 102 only upon instructions from the user.

If no interaction with the interactive digital sign 102 is desired orrequired, the method 1300 loops back to block 1302 to continue tomonitor for nearby interactive digital signs 102. However, ifinteractive with the interactive digital sign 102 is desired, the method1300 advances to block 1314 wherein the mobile communication device 104(and the user thereof) bi-directionally interacts with the interactivedigital sign 102. As discussed above, the interactions between the userof mobile communication device 104 and the interactive digital sign 102may be embodied as one or more different types of interactions, whichmay occur sequentially or contemporaneously with each other. Forexample, in block 1316, the user may view digital advertisementspresented on the display 208 of the interactive digital sign 102 inresponse to the transmitted user data. The mobile communication device104 may also receive one or more digital advertisements from theinteractive digital sign 102 in block 1316, which may be stored and/ordisplayed on the mobile communication device 104. Similarly, in block1318, the user may view digital coupons presented on the display 208 ofthe interactive digital sign 102 and/or receive one or more digitalcoupons from the interactive digital sign 102, which may be storedand/or displayed on the mobile communication device 104. As discussedabove, in some embodiments, the digital coupons may be encrypted by theinteractive digital sign 102. If so, the mobile communication device 104may decrypt the encrypted digital coupon in block 1318. Alternatively,the mobile communication device 104 may store the digital coupon in itsencrypted state until the digital coupon is used wherein the encrypteddigital coupon is decrypted at the time of use.

In some embodiments, the user may operate the mobile communicationdevice 104 to submit textual, audible, and/or graphical requests to theinteractive digital sign 102 in block 1320. For example, the user maytext a request for information to the interactive digital sign 102.Additionally, the user may speak into the microphone 234 of theinteractive digital sign 102 to submit the request or speak into themicrophone 334 of the mobile communication device 104, which relays therequest to the interactive digital sign 102 via the bi-directionalcommunication link. If the user submits a request for directions, forexample, the user may view the directions, and any associated digitalmap, displayed on the display 208 of the interactive digital sign 102 inblock 1322. Additionally, in some embodiments, the interactive digitalsign 102 may transmit the directions and/or digital map to the mobilecommunication device 104, which is received in block 1322. The user maythen utilize the received directions and/or map to navigate to a desiredlocation. Additionally, if the user submits a request for otherinformation (e.g., information regarding local stores), the user mayview the additional digital information displayed by the interactivedigital sign 102 in block 1324. Again, in some embodiments, theinteractive digital sign 102 may also transmit the requested digitalinformation to the mobile communication device 104 in block 1324.

In some embodiments, the user may utilize the display 208 of theinteractive digital sign 102 as a remote display. For example, in block1326, the mobile communication device 104 may transmit digital graphicsand/or other multimedia data to the interactive digital sign 102 fordisplay or execution thereby. Such multimedia data may be embodied as,for example, digital video, digital pictures, static graphics, charts,presentations, textual data, audio recordings, music, sounds, and/orother multimedia data that may be displayed and/or executed by theinteractive digital sign 102. For example, in some embodiments, themobile communication device 104 may transmit a digital avatar to theinteractive digital sign 102 in block 1328, which is subsequentlydisplayed by the interactive digital sign 102. The user may interactwith the digital avatar to request information and/or perform otherinteractions with the interactive digital sign 102. In this way, theuser may utilize a personalized avatar or character. Additionally, insome embodiments, the user may interact with the interactive digitalsign 102 by playing a computer game. In such embodiments, for example,the mobile communication device 104 may transmit the computer game tothe interactive digital sign 102 (or request a computer game stored onthe interactive digital sign 102) in block 1330. In response, theinteractive digital sign 102 may execute the computer game andfacilitate the user's game play using the display 208 and, in someembodiments, the user's mobile communication device 104 as a controlleror the like. After the user has interacted with the interactive digitalsign 102, the method 1300 loops back to block 1312 in which the mobilecommunication device 104 determines whether to continue interaction withthe digital sign 102. In this way, the user may operate the mobilecommunication device 104 to interact with the interactive digital sign102 to receive and disseminate information as discussed above.

Referring now to FIG. 14, although the interactive digital signs 102have been described above as “smart signs” capable of determininginformation for display based on the viewer's context and user datareceived from the viewer's mobile communication device 104, theinteractive digital signs 102 may be embodied as simple interactivedigital sign displays 1402 in other embodiments. In such embodiments,the determination of which information to be displayed and theprocessing of interactions from the viewer and/or the mobilecommunication device 104 are offloaded to a local interactive digitalsign management server 1406, which communicates with the interactivedigital sign displays 1402 over a local wireless network 1408. Forexample, the local interactive digital sign management server 1406 mayinclude the user interaction module 404, rather than each interactivedigital sign display 1402, and select which information (e.g., digitaladvertisement, digital coupon, or other digital information) should bedisplayed by each interactive digital sign display 1402. Additionally,the mobile communication device 104 may communicate with the localinteractive digital sign management server 1406 to interact with thedigital sign displays 1402, rather than the displays 1402 directly. Insuch embodiments, a single local interactive digital sign managementserver 1406 may control one, two, or more interactive digital signdisplays.
